Why are graphite foils best used for the heat dissipation of precisely located heat sources ?
Graphite foils show in their graphite structure a strong anisotropic characteristic of the thermal conductivity. Through a very high conductivity in the plane direction (X-Y) and a high conductivity in the through (Z) direction, heat and precisely located heat sources are ideally dissipated with a specific orientation of heat flow, hence preventing hot spots.
